5Claims. (ca. 22140) -'Ihisfinvention have. to dispensing devices.

The invention has for an object the provision of a device adapted to besecured to the threaded neck of a' tube, such as the, neck of a collapsible tube holding tooth paste, shaving cream, or.

' other substance, adapted to'be exuded through ed neck and adapted toallow the opening or the the neck when the tube is rolled or otherwisecompressed, said dispensing device taking the place of the ordinary capreceived on the threadneckto be positioned so that material may beexuded therethrough or, upon releasing the tube,

. to permit the-tube to have the neck thereof automatically closed.

The present device contemplates the use of a bracket adapted. to besecured to some object,

and a pair of arms pivoted to said bracket, one

of whicharms is threaded for, engagement with the threads of the neckoi! a collapsible tube, and the other oi. whicharms cooperates'with theend of theneck to close the opening in the same, the

relationship being such that when the tube is a manually moved, the tubecarrying arm will move with said tube away from the closure arm and whenthe tube is allowed to drop under gravity,

the closure arm is positioned directly over the I One dimculty withdevices now known to the inventor which are adapted to take the place ofthe usual cap on tubes is due to the expense of constructing such adevice. The present inv vention is very cheap to manufacture in that itcosts but a few cents and can, therefore, be'readily placed in a box bythe manufacturer or seller of dental or shaving creams without greatlyadding to the normal expense of the cream.

In the drawing Figure 1 is a side elevation of the device, a certainportion being shown in section to illustrate connection of the devicewith the threaded neck of a collapsible tube,

Figure 2 is a front elevation of the device associated with acollapsible tube,

a Figure 3 is a fragmentary side elevation of the device, the tube beingraised so that the content thereof may be exuded through the neck uponcompressing the tube, and,

Figure 4 is a sectional view on the line 4-4 of Flgurel.

Referring now with particularity to the drawing, I indicates theimproved dispensing device as anentirety, and 2 a collapsible tube ofthe type employed for dental and shaving creams;

and wherein 3 is a threaded neck of said tube.

The device I includes a bracket 4 which may have two ofiset parallelportions 5 andiiwith an integrally formed connecting piece I, theportion 5 having through bores whereby screws may be passed therethrough"and received in some supporting member 8, thereby holding the bracketin substantially a vertical position. The portion 6 of said bracket isprovided with a transverse bore 9 and the end of said portion providedwith a shoulder III. A pair of arms ii and i2 are swingingly secured onopposite sides of the por- .tion .5 of the bracket through the medium ofa stud-or pin i3. 'The arm II is given a structural twist at I4 andprovided with a threaded bore i5 adapted to receive the threaded neck 3of the tube 2. The arm. II is termed the tube carrying member. The armi2 is given a structural twist at 16 and formed with a concave-convexprotuberance I! which when the arms are cooperating, isin alignment withthe threaded opening ii. A coil spring i8 has one end thereof passedthrough an opening in the part 6 of the bracket, shown at l9 in'Figure2, and the opposite end of said spring is passed through an opening inthe arm l2, as shown at 29. This coil spring at all times urges the armto swing in a clockwise direction relative to the bracket, rotationbeing limited by the arm engaging the shoulder ill, see Figure 3.

The operation, uses and advantages of the invention just described areas follows:

The bracket is mounted so as to be in a vertical position relative tothe supporting member 8, as shown in Figures 1 to 3, inclusive. The capthat is usually supplied with collapsible tubes is removed, and the neckthreaded into the threaded opening l5 of the arm II. This operation isconveniently accomplished by swinging the arm II tothe position shown inFigure 3. Upon dropping the-tube, the same will fall under gravity and aportion of the neck of the tube which projects beyond the surface 2iwill be received within the confines of the member I! as, for instance,illustrated in Figures 1 and 4. When the neck is received as aforesaid,the arm i2 will be moved from engagement with the shoulder ill, seeFigure 1. It will be remembered that the arm i2 is spring actuated sothat the portion I i is at all times urged to cover the outlet of theneck of thetube.

When it is desired to dispense any of the ma-- terial from the tube, thetube may be swung, together with the arm ll, about the pivot point ofsaid arm to the position shown in Figure 3, whereupon pressure upon thetube will cause the contents to be exuded therefrom, as indicated by thedotted lines at 22. When the tube is dropped, any extra material at theoutlet end of the neck of the tube will not be removed therefrom by themember I! unless, of course, considerable of the material .from saidtube was left projecting from the opening in the neck. It is expectedthat the user of the devicewiil, under ordinary circumstances, wipe thetube clean with a brush or other article so that pastewill not build upwithin the member l1. However, it is evident that even if the materialdoes build up within the member I! that the construction of the deviceis such that direct air contact with said material is prevented so thatthe material will not dry and become hard;

I claim:

1. In a device of the character disclosed, a bracket adapted to bevertically, secured to a supporting structure, a pin carried by one endof said bracket, a pair of arms positioned on opposite sides of saidbracket and swingingly mounted on said pin, one of said arms formed witha threaded bore for threaded engagement with the neck of a collapsibletube and the other of said arms provided with a concave-convex cap, andmeans normally urging said last named arm to position said cap over thethreaded opening of the other arm.

2. In a device of the character disclosed, a bracket adapted to besecured to a supporting structure, an arm swingingly mounted at one end01 said bracket, said arm formed with a threaded bore to receive thethreaded neck of a collapsible tube and said arm normally being swungfrom a vertical position under influence of gravity when a collapsibletube is secured thereto; a second arm swingin lv mounted to saidbracket.

said second arm formed with a concave-convex structure, an armswingingly mounted at one end of said bracket, said arm formed with athreaded bore to receive the threaded neck of a collapsible tube andsaid arm normally being swung from a vertical position under influenceof gravity when a collapsible tube is secured thereto; a second armswingingly mounted to said bracket, said second arm formed with a'concavo-convex cap, resilient means urging said arm and its cap tooverlie the opening of the first arm and the neck of any tube securedthereto. and stop means for said bracket for limiting movement of theresiliently urged arm in one direction.

4. A device of the character disclosed, including a bracket adaptedto bevertically secured to a support, a pin carried by said bracket, a pairof arms swingingly mounted on said pin, one of said arms being formedwith a threaded bore into which the threaded neck of a collapsible tubeis screw seated, said other arm being formed with a cap to receive theprojecting end of the neck of said collapsible tube when said first armis swung against said'second arm, under the influence of the weight ofsaid collapsible tube, and a spring coiled around said pin with one endof said spring connected to said bracket and the other end of saidspring connected to said second arm for urging said second arm towardsaid first arm to position said cap over the projecting end portion ofsaid neck of said collapsible tube.

5. A device as claimed in claim 4 including a stop on said bracket to beengaged by said second arm to limit the movement of said arm under theinfluence of said spring.
